Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718930, here are decompositions:

13 + 8718917 = 8718930
23 + 8718907 = 8718930
43 + 8718887 = 8718930
53 + 8718877 = 8718930
61 + 8718869 = 8718930
71 + 8718859 = 8718930
79 + 8718851 = 8718930
97 + 8718833 = 8718930

Showing the first eight; more decompositions exist.
